All I can say is I'm amazed so few people are having issues with the service. As a Web Developer (Specifically, a C# desktop, web-plugin, and web-service developer) I know just how hard it is to make things work using something you've written yourself simply to display the right website for the user.
Metaboli are using a third-party system - note that, they haven't written the Yummy player, they licence it from
Yummy - which has its relatively minor stability and management issues. Yes, I say relatively minor, because it's something that you can fix with basically a re-install. I'm sure they're putting as much pressure on Yummy to fix these issues as we're putting on them to get them sorted - but bear in mind that this is an immensely complicated system.
There are many things interacting here - the OS (XP/Vista/Windows 7), the browser (IE/Chrome/Firefox/Safari/Opera), the version of Java installed, the specific game, the users permissions levels (UAC on/off; local administrator/not)... add to that the additional thought that even in one browser, things change significantly from version to version, and you've potentially thousands of combinations of the major features. Then add in the graphics card family (Intel/AMD/Nvidia), Graphics card driver version, sound card, network type (wired/wireless), DirectX version, PhysX and all the other combinations and features... Throw into the mix the additional frustration of Windows Updates, which change the operation of features depending upon security concerns...
Another thing to think about is the fact that these are community forums. They're not specifically for Metaboli to assist - though they have done; they're for user-to-user assistance. The support e-mail address is for Metaboli assistance, and they're reasonably good at responding to that.
I'm prepared to knock bad service when I see it (Don't get me started on T-Mobile, O2 or BT), but from Metaboli I see a small company who's doing a decent job. I should know - I work in a small company who's likes to think it's doing a decent job
